What is the diagnostic code for IAT sensor circuit high input?
P0113 is a diagnostic trouble code (DTC) for “IAT Sensor Circuit High Input Problem”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
Where is the IAT sensor located on a car?
The P0113 occurs when the PCM reads a high voltage signal in the IAT circuit. On most cars the IAT is located in the air intake box. Look around the intake box for a cylindrical shaped object with a two wire lead. If you don’t find two wires, the IAT may be integrated with the MAF sensor.
What does IAT stand for in forced induction engine?
Forced-induction engines have two IAT sensors. Usually, IAT or IAT1 refer to the sensor measuring air temperature coming into the mass air flow (MAF) meter. Because air temperature increases under compression, from the turbocharger or supercharger, sensor IAT2 is used to measure air temperature after just after the compressor.
What should the IAT reading on the scan tool be?
The IAT temperature reading on the scan tool should be maxed out at the high end. For example it should be 280 degrees Farenheit or higher. If it is, the wiring is okay, and it may have been the connection. If it isn’t install the jumper wire between the IAT signal circuit and the chassis ground.
